Baltimore Ravens: Ted Marchibroda

Record: 16-31-1

The Baltimore Ravens have only had three head coaches, and Marchibroda is the only one of the three to never reach the playoffs.

Marchibroda had a long coaching career before he became the first Baltimore Ravens head coach. He had success coaching the Colts in Baltimore in the 1970s and later in the '90s with the Indianapolis Colts.

The year before being hired by the Ravens, Marchibroda led the Colts to the AFC championship.

However, despite prior NFL coaching success, Marchibroda struggled as the Ravens head coach.

Marchibroda's successor, Brian Billick, would win the franchise's only Super Bowl just two years into the job.

New York Jets: Rich Kotite

Record: 4-28

Hiring Kotite was a decision that made sense for the Jets. He had some success while coaching the Philadelphia Eagles, as they were 21-11 in his first two seasons. Kotite was also a New York native and born in Brooklyn.

However, absolutely nothing went well for Kotite as coach of the New York Jets.

The true indictment of Kotite as the worst coach in Jets history is the team's instant success after his firing. The first season after his dismissal, the Jets went 9-7, and the next year they made the AFC Championship Game with a 12-4 record.

Kotite, like Dave Shula, never coached football again after his dismal tenure in New York.

Miami Dolphins: Cam Cameron

Record: 1-15

Cam Cameron was hired to be the head coach during a rebuilding period for the Miami Dolphins, following former head coach Nick Saban's resignation to become the head coach at Alabama. He was signed to a four-year, $10 million dollar contract.

Just one year in, he was fired.

Cameron and the Dolphins started 0-13 before getting their first win. Making matters worse for Cameron, the Dolphins went 11-5 the following season under Tony Sparano.

Cameron is currently the offensive coordinator for the Baltimore Ravens.

Denver Broncos: Josh McDaniels

Record: 11-17

McDaniels' coaching woes in Denver took place both on and off the field.

Before coaching a game for the Broncos, McDaniels attempted to trade Pro Bowl quarterback Jay Cutler for Matt Cassel. After the trade broke down and became public, the Broncos had to trade Cutler to Chicago.

In McDaniels' first season, the Broncos started 6-0; however, the team finished the remainder of the season 2-8. More controversy arrived toward the end of the 2009 when McDaniels benched Brandon Marshall, which led to him being traded to Miami.

The following season, McDaniels and the Broncos began 3-9. With four games remaining in the season, the Broncos fired him.

The following season, the Broncos won the AFC West and advanced to the second round of the playoffs.

McDaniels landed on his feet after being fired, as he is currently the offensive coordinator for the New England Patriots.

San Diego Chargers: Mike Riley

Record: 14-34

Mike Riley's first season coaching the Chargers, like a few coaches on this list, started off well. The Bolts went 8-8 with a 5-1 conclusion to the season. This created a false sense of excitement for Chargers fans.

The following season, 2000, the Chargers were 1-15, the worst record in Chargers history.

The dismal season was followed by another disappointing season. The Chargers went 5-11, after which Riley was fired.

Oakland Raiders: Norv Turner

Record: 9-23

Picking the worst coach in Raiders history is no easy task. Tom Cable, Lane Kiffin and Art Shell (his second time coaching the team) all made cases to be the worst coach, but the award had to go to Norv.

In his two seasons as head coach, the Raiders resisted any semblance of competitiveness. Each season contained five-game losing streaks.

Turner, of course, is now the head coach for the San Diego Chargers, where he got consideration for that team's worst coach in history based on the destruction of San Diego's once-impressive roster.

Houston Texans: Dom Capers

Record: 18-46

Capers was given the tricky task of becoming the first coach for the expansion Texans.

It didn't go well.

Considered a defense genius, Capers failed to achieve a winning season. His defenses ranked in the bottom fourth of the league each season, while his offense set the record for most sacks allowed in a single season.

In his final season, Capers etched a 2-14 record.

Despite all his failures, Capers was able to beat the cross-state foe, the Dallas Cowboys, in the team's franchise opener. This did not make Jerry Jones very happy with his coach at the time, who (spoiler alert) will appear as the worst coach in Dallas Cowboys history.

Capers is currently the defensive coordinator for the Green Bay Packers.

Green Bay Packers: Bart Starr

Record: 52-76-3

Bart Starr on a list of worsts? Yes, it may be hard to imagine, but the legendary player was a stinker of a coach. In his nine seasons as head coach, he only made the playoffs once, which was during the strike-shortened 1982 season that featured a 16-team wild-card format.

Chicago Bears: Dick Jauron

There have been coaches in Chicago Bears history with worse records then Jauron, but he is the worst coach they've had.

Hired in 1999, over Jauron's first two seasons the Bears were a dismal 11-21. In 2001, the Bears went 13-3, which might compel you to ask how Jauron could be on this list.

Well, in that year's playoffs, the Bears got smoked at home by the Eagles.

The next season, a season where the Bears were considered contenders for the first time since Mike Ditka, Jauron managed to post a 4-12 record with many of the same players on the roster as the 2001 season. He would get fired a year later.

Take out Jauron's 13-3 season and his record is 22-42.

Jauron would later be the head coach in Buffalo and is now the defensive coordinator for the Browns.

Detroit Lions: Marty Mornhinweg

The Lions famously went the entire 2008 season without a victory. Yet coach Rod Marinelli is not the worst coach in franchise history, thanks to the incompetence of Mornhinweg.

Outside of his lowly record, Mornhinweg's unpleasant tenure in Detroit is marred by the worst coaching decision in the history of the profession.

In a Week 12 game against the Chicago Bears that went into overtime, Mornhinweg elected to kick the ball after winning the coin toss. Lest we not forget that this act of idiocy was before the overtime rule change; overtimes were still sudden death.

The Bears took possession, kicked a field goal and won the game.

To no one's surprise, Mornhinweg was fired following the season. He is now the offensive coordinator for the Philadelphia Eagles.

Minnesota Vikings: Les Steckel

Record: 3-13

Historically, the Minnesota Vikings have been extremely consistent. Since the merger, only three of their coaches have posted sub-.500 records. One of those was Mike Tice, who was only a game under; the other coach is current head coach Leslie Frazier.

Steckel had the unfortunate responsibility of following the legendary Bud Grant.

His one season as head coach is the worst in franchise history, and he was fired thereafter.

Dallas Cowboys: Dave Campo

Record: 15-33

Campo is the only Cowboys head coach with a sub-.500 coaching record.

In his first season with the Cowboys—the final for quarterback Troy Aikman—the team went 5-11. The next season followed suit, as the Cowboys again went 5-11 and were riddled with issues at quarterback. Ryan Leaf even started a game for this team.

If Campo was anything, he was consistent. In his third and final season, the Cowboys again went 5-11. As previously mentioned, he lost to the upstart Houston Texans in the first game of the season.

Carolina Panthers: Geore Seifert

Record: 16-32

Of the four head coaches the Panthers have had, Seifert is the worst.

Seifert's lackluster performance as the Panthers head coach deflated his coaching pedigree as a two-time Super Bowl champion in San Francisco. Seifert's first two seasons in Carolina were disappointing, but not complete failures, as he went 15-17.

The Panthers completely deteriorated during Seifert's third season in Carolina, as the team went 1-15. In his defense, his quarterback was Chris Weinke.

John Fox took the Panthers to the Super Bowl two seasons after Seifert was fired.

Arizona Cardinals: Dennis Green

Dennis Green had great success coaching the Minnesota Vikings. It didn't translate to Arizona.

The best thing that came out of Green's tenure in Arizona was the memorable meltdown after the Bears miraculously came back and beat the Cardinals, despite trailing 24-3 in the fourth quarter. He also started Matt Leinart over Kurt Warner.

Leinart, to the demise of Green, was not at all who he thought he was.

Furthering Green's woes, his successor made the Super Bowl with Kurt Warner at quarterback two seasons after Green was fired.
